Biolage is my HG conditioner! I really don't find anything else as moisturising. Mastey Moisturee is nice though.
After using both the BB & Giovanni conditioners I felt the need to put another conditioner on. I did get fairly good detangling with both. So not as moisturising as Biolage.
MOP Mixed Greens might also be worth a look. Bit pricey though at around $23.
My main aim is lots of moisture and I am aiming for my curl to be squashed down a bit!
How are you using the Biolage?
